Have an iPad? The Healthy, $29 Investment That May Help You Sleep Like a Baby

If you have an iPad (or other tablet-style computer), and find that you use it in bed before you go to sleep, you might find that you toss and turn more than usual. Researchers have proven the connection between iPads and poor sleep, but there's something you can do about it...

Do you find that you brush your teeth, get in your PJs, then lay in bed with your iPad for a while before trying to doze off? The iPad could be messing with your sleep, say experts. Researchers in New York found that iPads, and other tablet-style devices, may reduce the bodies natural sleep-inducing hormone, melatonin, by as much as 22 percent, which is enough to keep you tossing and turning and interrupt your normal circadian rhythms. (Good news: They also say that your iPhone is too small to have the same effect!)

The solution? You could always limit computer time at night, or invest in a cheap, blue-light filter, like this one that retails for $29, which can effectively reduce the amount of melatonin-zapping blue lights.
